hi, im very new to this, but i was able to get most of this to work. I have an xvid avi file with ssa subtitle file, i was able to hardcode the ssa file into the video using virtualdub, and i want to save it as one complete avi file to burn it on VCD, however the anticipated capacity of the filtered file would be over 800,000 mb! I dont know what im doing wrong...someone please help.

hmmmm, when i opened the video file i got this:
"Virtualdub has detected an improper VBR audio encoding in the source AVI file..."
"virtualdub will rewrite the audio header with standard CBR values..."
"This may introduce up to 23721 ms of skew from the video stream"
"(bitrate: 125.7 (plus or minus)* 16.4 kbps))

the above are just fractions of the message, it tells me how to fix it if i find it unacceptable, which i do because the audio starts a tad faster than the video, it says i have to decompress the entire audio stream into an uncompressed wave file and then recompress with a constant bitrate encoder. all of this i do not understand how to do.

*the plus minus part is a written interpretation of the symbol, which is a plus sign on top of a minus sign.
